Which Samsung Galaxy for Zwift

Hello everyone. I have an urgent question. Until now I used a Samsung Galaxy A40 in combination with a Chromecast for Zwift. Worked perfectly until after the latest Zwift updates. Now this isn’t going well. Imaging refreshes in jumps and so on. It still runs well on an A70, but they are phasing out. So I’m going to buy a new smartphone. Who is currently satisfied with their Samsung and which model are you using? Resolution, frame rate etc…
Thanks for your reply
